# Private key, Public key & Address
IoTeX's Private Key is 64 random hex characters, e.g.,
90bf89cd944df5c6d8281b132783277c1760537809c534fc54dda34c4edfb4f4, and the corresponding Public Key is derived from the private key using ECDSA (secp256k1), which is exactly the same as Ethereum.
Given a signed message, you can recover the public key of the signing account using this tool (opens new window).
# Address Construction
A IoTeX human readable address like
io1nyjs526mnqcsx4twa7nptkg08eclsw5c2dywp4 can be constructed using the following steps:
Generate a random private key and the corresponding public key using 's elliptic curve;
Apply hash function to the public key, exluding the first byte:
Take the last 20 bytes as the payload: , which is the byte representation of the address;
Apply bech32 (opens new window) encoding on the payload, and add the
